Perhaps one of the most important areas for tactical research at the moment is to investigate the potential applications and specific methodologies for collaborative learning. This research should look at the tools available and also the tools that would be desirable for collaborative learning. These may include shared workspaces, the sharing of documents, and even virtual-reality possibilities of being in almost physical contact with collaborators who are in reality at a distance.
A second area of important research for the future is the design and evaluation of specific CMC environments for the effective implementation of particular types of instructional activities. These may include simulation games, small-group discussions, group assignments, or case study discussions. These techniques, which are typically practiced in small-group discussion situations facilitated by a skilled expert, are among the techniques that are most valued for the development of critical thinking, problem solving, and other higher-order cognitive skills.
